21. Thus, there is a subsequence of ( x _ n ) which converges to x. 22. More complex instructions required several subsequences . 23. Each entry contains the leading terms of the sequence, searchable by keyword and by subsequence . 24. Formally, an-gram is a consecutive subsequence of length of some sequence of tokens. 25. The existence of weakly convergent subsequences is a special case of the Eberlein ` mulian theorem. 26. In particular, the sequence of points has no subsequence that converges to any given real number. 27. Each timing pulse in a subsequence could trigger up to 5 " control pulses ". 28. Note that while a sequence is a net, a sequence has subnets that are not subsequences . 29. The algorithm correctly reports that the longest common subsequence of the two files is two lines long. 30. A Banach space is reflexive if and only if each bounded sequence in has a weakly convergent subsequence .
